When most people first learn guitar, they learn how to play. Very few people learn the basic maintenance skills for guitar until a later time. However, most people in the beginning use cheaper guitars that are not made by world class crafts men. This simple little thing will hold your guitar together and keep it in top notch condition. Even expensive model guitars sometimes need this maintenance.
When you sit down some time to change strings or there is nothing else to do, bring out one of your screw drivers and check all the screws on your guitar. Check the screws in the back of the guitar neck, the ones that hold the neck to the body. Check the screws on the pick guard. One of the most common places to find loose screws is the strap lock, especially if you play a lot with a strap. This will ensure your guitar is solid and firmly together.
It is also a good idea to check the screws on your tuners. These should not be tight, because that will prevent you from tuning your guitar, however they should not be loose either. It is best to adjust these with strings on the guitar and test them as you adjust. This will help your guitar stay in tune and it will make it easier to tune your guitar.
You do not need to do this a lot. A good time to check the screws on your guitar would be when you notice a screw looking or acting loose, and if this doesn’t happen check it once every year to 2 years.
Just one warning, make sure the screws are snug, but not too tight. Your guitar is made of wood and if the screw is too tight it can cause damage.
